Internal meshing cutter head harmonic gear SHG-20-160-2SO, a flexible wheel with external teeth that can produce radial elastic deformation when working, and a wave generator with elliptic shape and flexible rolling bearing on the outer ring mounted on the internal transmission part of the flexible wheel. The number of external teeth of flexible wheel is less than the number of internal teeth of rigid wheel. When the wave generator rotates, the outer teeth of the flexible wheel corresponding to the long axis direction just completely engage the inner teeth of the rigid wheel

In this kind of transmission, the worm gear as the basic part is the ordinary involute cylindrical gear (usually helical gear), which can be easily and accurately manufactured. Need not prepare worm gear hob separately. Hemernaker internal meshing cutter head harmonic gear SHG-20-160-2SO is used to process worm gear. The helical gear shaper with worm gear parameters * or the cutter head with only a few teeth is not difficult to prepare
When hardened worm is matched with Qingtong worm gear, after running and wear, there will also be hollow pocket on the tooth surface of the camshaft. After analysis, this is the secondary contact phenomenon at the entrance end of the worm. Therefore, this kind of drive can also be further developed into gradually open surface secondary enveloping ring surface worm drive, which is expected to have great potential in carrying capacity.
Axial movement of cone worm can adjust the clearance of tooth side without destroying the conjugate of tooth surface. Can also be used as a clutch, the combination and disengagement are very flexible, disengagement center distance remains unchanged. The internal meshing cutter head harmonic gear SHG-20-160-2SO is compared with the cylindrical worm drive, and the cone worm drive is stable, with large bearing capacity, high efficiency and compact structure when the transmission ratio is large
The relative sliding speed between tooth surfaces of cone worm transmission is larger. The main failure forms are still tooth surface damage, such as tooth surface grinding, glue and developmental pitting corrosion. The internal meshing cutter head harmonic gear SHG-20-160-2SO can cause tooth breakage only under the condition of large overload. The strength calculation of cone worm drive comes down to the durability calculation of tooth surface.
In order to save energy and material, high efficiency and miniaturization are required for gear transmission. Since the planetary gear drive basin uses several planetary gears when transferring load
